APPARATUS FOR MANUFACTURING MERCURY BICHLORID.

Patented Dee. 3i), 1913.`

Original application led August 27, 1912, Serial No. 717,246. Dividedand this application filed March 19, 1913. Serial No. 755,377.

T0 all 'whom t may concern Be it known that we, FELIX KAUELER, a subjectof the Emperor of Austria-Hungary, and resident of Brckl, Carinthia,Austria-Hungary, and AUGUST KLAGES, a subject of the German Emperor,King of Prussia, and resident of Salbke, in the Province of Saxony,Kingdom of Prussia, German Empire, have invented new and usefulImprovements in Apparatus for Manufacturing Mercury Bichlorid, of whichthe' following is a full, clear, and exact specification.

The invention relates to apparatus for preparin mercury bichlorid by thedirect action o chlorin gas or mercury; and the present application `isa division of a prior vapplication filed by us on the 27th -day ofAugust, 19.12, Serial No. 717,246, in which the' invention is shown anddescribed but not specifically claimed. It has for its object to provideapparatu suitable for continuously burnin mercury in a current ofchlorin gas and wich apparatus may be closed and of small size, wherebythe same may be readily surveyed and escape of the mercury bichloridvapors prevented. Danger to the workmen ,is thereby obviated, thebichlorid being obtained as a finished commercial product, requiringr nocrystallization, sublimation or drying of the poisonous substance.

The invention has for its object, furthermore, to obtain mercurybichlorid in an extremely nely divided state and thereby avoid thetroublesome pulverization of the solid mass, the product thus obtained,moreover, being chemically pure, of brilliant white color and much morevoluminous than that heretofore obtained.

In the accompanying drawings, the apparatus employed for the productionof mercury bichlorid is represented in side elevation, partly insection.

a designates the retort preferably consistin of quartz glass andprovided with a ch orin admission tube b ending above the level of themercury@ contained in the retort, and a mercury admission tube dterminating below the level of said mercury.

Both .tubes b and d, are also preferably made of quartz. As shown in thedrawing, the mercur admission tube d can be disposed within the chlorinadmission tube t), the mercury flowing through the tube d being thuspreliminarily heated `by the chlorin at the open end of the tube Z1,before sai mercury enters the mats of mercury c. Both tubes may beprovided with suitable valves e and f' for regulating the admission ofthe chlorin and mercury, respectively.

rlhe retort is heated by suitable means. In the drawing a gas burner gis shown, which may be of any' desired construction. Other heatingdevices, for instance electric heating appliances, may be used. l

The mercury lbichlorid formed in the retort may be discharged throughthe outlet tube h into a large tower z', which may be ot anysuitable-material not attacked by the mercury bichlorid v apors. havefound it preferable to luse glazed7 acidproof bricks. Into this towerair is admitted by means of a tube 7c provided with flame burning .asuitable regulating valve l, the air being preferably mixedV with asmall percentage of chlorin, not exceeding say 10%. Thetube c preferablyterminates near the end of the outlet tube L. Thus the air becomes mixedbichlorid it is preferable, though not absolutely necessary, to providea second tower n connected to the tower i by means of a tube 0..V rlhetower n may also be provided with a man-hole and cover p. In this tower,

-. which may be made of clay, the last traces of mercury bichlorid aredeposited. The

apparatus is, furthermore, provided with a tube g connected with asuitable suction device (not shown). Generally it will be sufcient toconnect the tube g with a chimney; or instead of suction devices, thegases may be introduced under pressure.

The process is rendered continuous by passing the current of chlorin gascontinually through the apparatus, and in constantly admitting freshquantities of mercury tothe chlorin flame, burning above the boilingmercury level, by allowing the mercury, which has preferably beenpreliminarily heated by the said chlorin flame, to enter below the levelof the boiling mercury. The reaction is assisted by gentle heating Inpractice wev andthe Whole reaction vessel is iilled with la brilliantgreen flame. The bichlorid thus tals are much more voluminous than the`product obtained heretofore vby the usual processes, one liter of themercury bichlorid thus obtained weighing only 1400 grams, whereas theusual powdered mercury bichlorid weighs 2800 grams per liter.

We do not limit ourselves to the l details of the apparatus shown, whichmay be varied in practice. without departing'from the scope of theinvention.

We claim 1. In an apparatus for burning a liquid in a gas thecombination of a retort, a as admission tube, a liquid admission tu e,terminating below the normal liquid level in the retort and locatedinside the gas admission tube, an outlet tube for the productofcombustion, and means for-heatmg thegre-V tort.

2. In anapparatus ,for` manufacvzturing mercury bichlorid the'combination of," a quartz retort, a quartz admission tubefor chlorin anda quartz admission tube 'for mercury, the latter terminating below thenormal mercury level in the retort and loheating the retort, and meansfor condenscated inside .the chlorin admission tube, an

outlet tube for the mercu bichlorid formed in the retort, and means orheating the retort.

3. In apparatus for l manufacturing mercury4 bichlorid the combinationofa retort, a chlorin admission tube,a mercury admission tube, an outlettube for the mercury blchlorid vformed in the retort, means for ing themercury bichlorid vapors,

4. In an apparatus for manufacturing mercury bichlorid the combinationof a retort, a chlorinA admission tube, a mercury admission tube, anoutlet` tube for the merfcury bichlorid formed in the retort, means forheating the retort, a tower into which the `outlet tube opens, and meansfor introducing a current of air into said tower to chill the vaporsfrom said retort.l

5. In an apparatus for manufacturing mercury bichlorid the combinationof a rei tort, a chlorin admission tube, a mercury admission tube, anoutlet tube for the mercury bichlorid formed in the retort, means forheating the retort, a tower into which the outlet tube opens, and meansfor introducing air into said tower in a jet discharging across theretort discharge tube.

6. In an apparatus for manufacturing mercury bichlorid the combinationof a retort, a chlorin admission tube, a mercury admission tube anoutlet tube for the mercury bichlorid v`formed in the retort, means forheating the retort, and a tower into which the outlet tube opens, and anair admission tube opening into the tower and terminating near the endof the outlet tube Ito chill the vapors from said retort.

7. In an apparatus for manufacturing mercury bichlorid the combinationof a quartz retort, a quartz admission tube for chlorin and a quartzadmission tube for l mercury, the latter terminating belowy the normalmercury level and located inside the chlorin admission tube, an outlet`tube for themercury bichlorid formed in the retort, means forregulating the admission of chlorin and mercury, means for heating theretort, 'a condensing tower of glazed acidproof bricks, andan airadmission tube opening into the tower and terminating near the end ofthe outlet tube to chill the vapors from said retort.

In testimony that we claim the foregoing as our invention, we have si edour names in the presence of two subscribin witnesses.
